I disagree to some extent.......diesels do take longer to "spool up" so the 0-36 mph time will suffer, but it should "hold" speed rather well (good for slalom), get 2-3 times the fuel economy of a gas V-8 and last much longer too. It would be a great engine choice in a wakeboard boat (heavy, ballast). I know diesel is the way to go for alot of reasons in europe.

Did you consider a 5.7 liter V-8 powered by propane? I know that's a good combo in europe as well.

BTW, that gelcoat is looking good! 2-week project? That's awesome! Looking forward to the pics as things progress.

Carpe Diem!

Thats also a rather high RPM diesel, so perhaps the spool up time will be lessened somewhat.

On the positive side, diesels have tremendous low end torque so that may have some hole shot assistance.

Can't say anything before finding the exaxt prop and testing it in the sea
Transmission ratio is 2:1 which is not good that is I know but I will try to find a big prop with a high pitch.Other then that the engine is a 6 cylinder 3.2 liter gives max 440 Nm Tork at 3300 Rpm.
I atttached the engine data in Pdf.

440 NM = 324.48 Lb/Ft is what this engine produces.


RTP engine 310 HP 360 ft.lb. (488NM)
MCX engine 350 HP 380 ft.lb.(515NM)
VW TDI 225HP 335 lb (454NM)
1 foot-pound is closely equivalent to:1.3558179483314 newton meters

I think in respect to fuel economy and performance ,overall we will get a 4/5.

Thanks for the comments.

Nj,It took about 2 months to find this engine,those engines are not still show up in the 2nd hand market,this engine was at 600hr and year 2002 that is why we chose it.
For the progress check the pictures .

Name Stickers were for registration,we will work on something look nice with decals .

Inmar is using the same engine with 256HP,mine is 236.

I am pulling for ya! Hope you can make that combination work with some trial and error in the prop selection.

JLeuck,I am really not sure about the end result,but made comparison with the figures above.I will post all the results here.

Check out the pictures.

Wow, looks great.

Very interesting using a turbo diesel in that boat. Do you think that the turbo is going to stay cool enough not to melt the engine box? I'll bet you can swing a rather large prop with a high pitch with that torqy motor. Do you know what the motor came out of?
